The aircraft carrier in the region, the USS George H.W. Bush, has F/A-18 Hornets, which are what the administration is using for surveillance flights right now. The carrier also has some MV-22 Osprey transport planes, which would be used to evacuate the thousands of personnel from the massive US Embassy in Baghdad.
